Planting Phlomis
Selecting the Right Location for Phlomis
Where to Plant: Choose a spot with full sun to partial shade. Phlomis, being a Mediterranean plant, prefers locations that mimic its native environment.
Planting Process for Phlomis
How to Plant:
- Dig a Hole: Ensure it’s twice as wide and the same depth as the pot.
- Check Depth: Place the potted plant in the hole to ensure correct depth.

Caring for Phlomis
Watering and Feeding Phlomis Plants
Watering: Regular watering is key, but be cautious of overwatering. Phlomis does not tolerate ‘wet feet’, especially in winter.
Feeding: Use a general, organic fertilizer every two weeks during the summer months.
Pruning and Maintenance of Phlomis
Pruning: Trim back in spring to maintain shape and encourage healthy growth. Avoid deadheading spent flowers as the seedheads add ornamental value.
Maintenance Tips:
- Soil Check: Ensure soil remains well-drained.
- Monitoring: Keep an eye out for leafhoppers, although they rarely cause significant damage.
Troubleshooting Common Issues
